The extension does not work
The extension supports webui version 1.1, 1.2,1.3 And the March 25 version
if you see this inscription you also need update webui or gradio.

If you have a webui other than auto1111, you need to check the version of gradio for the extension to work, it should be 3.23 or higher.
You can check the version of gradio in requirements_versions.txt file in the root folder.

Google collab
2)If you use google collab, check the box that says webui version, for example in fast_stable_diffusion_AUTOMATIC1111 , this checkbox downloads an older version of webui

You can also check the webui version at the bottom of webui

The gradio version must be higher than or equal to 3.23
The webui is lagging a lot
The problem is that your scale in the browser or windows is not 100%, check that you have 100%

The extension does not update
For some reason sometimes the extension does not update if you click the check for updates button, to fix the problem delete the canvas-zoom folder in extensions folder and install it again via the Extensions tab
The movement key ( F ) is stuck
Check if you have the "Automatically search the page text when typing" setting enabled in your browser and turn it off.
You can also use mouse+wheel(hold) to move.
I deleted the extension, but some elements of the extension remain
- in powershell or cmd Go to the folder
stable-diffusion-webui\venv\Scripts
- Enter the following commands
activate
pip uninstall gradio
pip install gradio
